I agree with this. The way to solve this is the way in which the CORBA
Trading Service solves the same problem: dynamic properties.

Basically in the .oaf file you would have:

<oaf_attribute name="bonobo:supported_mime_types" type="stringv"
resolver="OAFIID:GNOME_EOG_Factory"/>

And when supported_mime_types was queried for, it would activate the
factory and request a GNOME/OafDynamicProperty. ::evalProperty would be
called and passed the property name being queried for, and the typecode
of the result expected. 

The OafDynamicProperty impl could then query gdk-pixbuf (through yet to
be determined means :) and return the result, which would accurately
present which mime types EOG can support, plugins and all.
